Methods： HaCaT cells were treated with different doses of acitretin for 48 h, then the changes on the transcription of FGF10 mRNA and the translation of FGF10 protein in these cells were detected by immunofluorescence and in situ hybridization assay. Results： Compared with the control group, the transcription of FGF10 mRNA and the translation of FGF10 protein were gradually decreased along with the increasing dose of aeitretin. There were significant differences between different groups （P〈0.01）. Conclusion： Aeitretin could inhibit the transcription of FGF10 mRNA and the translation of FGF10 protein in HaCaT cells. With the dose of aeitretin increased, the stains of both FGF10 mRNA and FGF10 protein in HaCaT cells are reduced.展开更多

Methods： Data from 112 MCL cases were collected, and immunohistochemical assay was conducted. Fluorescence in situ hybridization （FISH） detected a break in the CCND 1 gene. The t-test was used in the statistical analysis. Results： All tumor cells in the 112 cases expressed B cell-related antigen, including 1 blastoid subtype and 1 polymorphic subtype. Among all cases, 106 expressed CD5 and 104 expressed cyclin D1. A break in the CCND1 gene was not found in 3 cases with CDS-MCL. IgH/CCND 1 polyploid was observed in 2 classic cases. Conclusion： MCL is a type of special immunophenotypic B-cell lymphoma, The prognoses ofblastoid and polymorphic subtypes are poor. Special subtypes should be classified during diagnosis.展开更多
